Hi Ponderings,
The author's name is Peace Pilgrim. The book was put together by her friends after her death in 1981. She gave up her given name when she started walking for peace in 1953.
I posted the Peace Pilgrim website in the Resources section of this website. You can read the entire book there or request a free copy. Amazon also sells it. I borrowed it from my local library. A great read in my opinion. Enjoy.
